Threshold Energy Of Laser at Minnie Butler blog

Threshold Energy Of Laser. A laser is device that emits coherent and monochromatic light. This is the case for a certain pump power (the threshold pump power ), or (for electrically pumped lasers) a certain threshold current. Instead three or four level energy systems are generally used (figure 5). The threshold gain is function of the parameters of the optical cavity. A laser cannot operate if the gain is smaller than the resonator losses; Three level processes involve pumping of population from the lowest energy level to the highest, third energy state. The lasing condition states that photons multiply. Significant power output is achieved only for pump powers above the laser threshold, where the gain can reach (or temporarily exceed) the level of the resonator losses. For a given laser, determine: In a two level energy system it is impossible to create the population inversion needed for a laser. Three and four level energy system.
